Can you check your config.log for mentions of clock_gettime ?

For example in mine I have:

  configure:25329: checking for library containing clock_gettime
  configure:25377: result: -lrt
  configure:25389: checking for clock_gettime
  configure:25389: result: yes
  configure:25389: checking for clock_settime
  configure:25389: result: yes

Odd.  To have gotten here you had to have built libguile already, which
indeed should have linked to -lrt.  Can you grep your libguile/Makefile

Is it perhaps that clock_getcpuclockid is in -lrt but clock_gettime is
in your libc?
